[framework]: `declare` when overriding a property does not change the property type

[tsanislavgatev]

Bug Description

We are extending the ListItem in MenuItem and we also override a property called accessibiltiyAttributes.
We create new type that is with

type MenuItemAccessibilityAttributes = Pick<AccessibilityAttributes, "ariaKeyShortcuts" | "role"> & ListItemAccessibilityAttributes

and we declare it like:

@property({ type: Object })
declare accessibilityAttributes: MenuItemAccessibilityAttributes;

We have an issue that when application developers are using the MenuItem and giving role, validators underline with error, because in our case, the documentation is not updated and the property type is still ListItemAccessibilityAttributes.

This is how the @custom-elements-manifest/analyzer works. The issue was addressed in the PR open-wc/custom-elements-manifest#300. While the discussion is ongoing, a patch was merged in #11162.

Now, everything is functioning as expected, as described in the issue.
